Alan Cohen joined us to talk about brain waves, medical product development, open source, and helpful engineering.

Alan has been working on VolksEEG (volkseeg.org, github.com/VolksEEG/VolksEEG). This is an EEG (wiki Electroencephalography) which detects brain waves. It uses the TI ADS1299 EEG monitoring chip and the Adafruit Feather nRF52840 Sense.

Alan wrote Prototype to Product: A Practical Guide for Getting to Market, published by O'Reilly. He talked about it on a previous episode: 269: Ultra-Precise Death Ray You can find him on twitter as @proto2product and on LinkedIn.

Helpful Engineering (helpfulengineering.org) aims to deliver more open source solutions to society's systemic challenges.

Chris and Elecia discuss civic duties, the CAN bus, fulfilling Kickstarter orders, and the answers to a series of questions about embedded systems.

Elecia was recently introduced to TRIZ inventive principles (wikipedia page) and started reading And Suddenly the Inventor Appeared: TRIZ: Theory of Inventive Problem Solving by Genrich Altshuller.

Elecia's typing robot

Jeremey had a neat way to go about solving a problem. He called it Dr. FARM:

• D Define the problem

• R Research other solutions, partial solutions, terminology

• F Function: what do I want it it do?

• A Appearance: what should it look like?

• R Risk: is anyone going to get hurt in manufacture and function?

• M Model: prototype the design

Liam Cadigan joined us to talk about founding a successful startup from a college capstone project. Liam is a co-founder of InspectAR and worked on the board files the system uses.

Liam can be found on LinkedIn and Twitter.

Alex Glow filled our heads with project ideas.

Alex is the Resident Hardware Nerd at Hackster.io. Her page is glowascii and you might want to see Archimedes the AI robot owl and the Hardware 101 channel. They have many sponsored contests including BadgeLove. You can find her on Twitter at @glowascii.

Lightning round led us to many possibles:

• It you were building an IoT stuffed animal, what would you use? Mycroft and Snips are what is inside Archimedes.

• If you were building a camera to monitor a 3d printer, what would you use? For her M3D Micro Printer, Alex would use the Raspberry Pi based OctoPi to monitor it.

• If you were going to a classroom of 2nd graders, what boards would you take? The BBC Micro:bit (based on Code Bug) or some LittleBits kits (Star Wars Droid Inventor Kit and Korg Synth Kit are on Amazon (those are Embedded affiliate links, btw).

• If you were going to make a car-sized fighting robot, what dev system would you use? The Open Source Novena DIY Laptop initially designed Bunnie Huang

There were more software and hardware kits to explore:

• Google DIY AI

• Arduino Maker1000

• Raspberry Pi Chirp.io

For your amusement Floppotron plays Bohemian Rhapsody

Alex gave a shout out to her first hackerspace All Hands Active

Ableton is audio workstation and sequencer software. Alex recommends Women's Audio Mission as a good way to learn audio production and recording if you are in the San Francisco area.

There is an Interplanetary File System and Alex worked on a portable printer console for it.

Elecia is always willing to talk about Ty the typing robot and/or narwhals teaching Bayes Rule. She recommended the book There Are No Electrons: Electronics for Earthlings by Kenn Amdahl.

Mario Marchese (aka Mario the Maker Magician) spoke with us about robots performing magic, humans performing magic, and writing a book about making magic.

You can find Mario on:

• His website mariothemagician.com

• YouTube (MariotheMagicianNYC)

• Instagram (mariothemagician)

• Twitter (@mariomagician)

• Facebook (mariothemagician).
